produced which must be reliably exhausted from the process chamber in order to avoid contamination and yield loss. However, since there is a wide variation in paste compositions associated with solar metallization, it is not always possible to customise a suitably effective filter or condenser to manage the released vapour or smoke.


Problem Solved


The introduction of Rehms Thermal Oxidiser uses an innovative thermal oxidation process to reduce emissions from solar dryers and firing systems during the metallization of crystalline solar cells. With the Thermal Oxidiser, emissions remain well below the statutory limitations for emissions of pollutants e.g. TA-Luft, Germanys Clean Air Act. The collection efficiency reaches 99.5%, making a significant contribution to lower maintenance costs for solar dryers and firing systems.


32 Noteworthy


In general, thermal oxidation systems can be used for almost all organic pollutants and are thus a very good alternative to condensate discharges. The main advantage over the condensate separation is significantly reduced maintenance costs of solar dryers and firing systems.


Innovation


In general, thermal oxidation systems can be used for almost all organic pollutants and are thus a very good alternative to condensate discharges. The main advantage over the condensate separation is significantly reduced maintenance costs of solar dryers and firing systems.


Customer Benefits


The main advantages of thermal oxidation are: reduction in maintenance costs, no disposal of condensate, secure compliance with the legal requirements for emissions, universally applicable for various metallisation pastes, proven, broadband method, robust systems engineering, low energy consumption, low operating costs, decreased odour of solar dryers.


Soldering Table


The soldering table is a stand alone soldering station for solar cells (identical soldering station as the Somont stringers) for material testing and qualification under production conditions. The station is compact and cost-efficient. New materials (cells, ribbons, flux) can be tested and verified much faster. This leads to a time and cost reduction for the process.


Challenge


Until now the R&D departments have been faced with following issue: If there has been f.i. a new cell development, this new cell has to be tested for solderability on the stringer. But the production has the target to produce a certain amount of modules/day. Consequently it is difficult for the R&D to get valuable production time on a stringer for testing new materials (cells, ribbons, flux...)


Customer Benefits Problem Solved


The soldering station is a cost and space saving solution for every laboratory /development department. The station delivers quality soldering results with high peeling forces. New developments (cells, ribbons, pastes, flux) can be tested more intense and without any time pressure on the soldering table and verified much faster afterwards on the stringer. This leads to a drastic cost reduction.


Noteworthy


The soldering table is a compact, cost- efficient tool, which can be set up in every laboratory/development department. No similar product on the market.


Innovation


The soldering table is the ideal tool for various target customers: For module, cell, ribbon, flux, paste manufacturers as well as institutes and laboratories. Until now most of the target customers have tested/soldered their new materials manually or as mentioned under point 1 on a stringer which is very expensive and difficult to get the testing time of the production. To draw conclusions from manual soldering/testing for later


The customer benefits are: - Cost effective - no loss of valuable production time / output - High quality and reproducible soldering results with excellent peeling forces due to Somont Soft Touch Soldering - Recipe pre- qualification and simulation - all stringer recipes can be pre-tested —> faster material validations are possible - Time saving for the R&D department - no more conflict of interests between R&D and production, no more waiting to get a stringer for testing new materials —> new developments can be introduced much faster on the market than in the past.


Flexible - a variety of different materials can be tested without any time pressure, test phases can be done more intense. Easy to handle due to intuitive HMI (same as on Somont stringers) to set up parameters. Space saving and fast reaction time to material changes. innovations on the market can be introduced and tested immediately.


automated stringer production is difficult. With the soldering table the customer receive reproducible soldering results with excellent peeling forces due to Somont Soft Touch Soldering. Testing phases can be done more cost effective (no more valuabe production time on the stringer is necessary anymore). Consequently testing phases can be done more intense without any time pressure. It is time saving as the customer does not need to wait to get a stringer in the production for his testing periods. Thus new developments can be introduced on the market faster.
